Mother Nature has seen enough of the Mets.

The Mets had their series-opener against the Phillies rained out at Citi Field on Friday, a day after their game against the Marlins was suspended on Thursday night.

The game versus Philadelphia is scheduled to be made up on Saturday as part of a single-admission doubleheader beginning at 4:10 p.m., although more poor weather is in the forecast, putting the twinbill in jeopardy.

Tickets to Friday’s game will not be valid for Saturday’s doubleheader.

With the Mets long out of the playoff picture and the Phillies locked into the top wild card spot in the National League, the three-game series won’t be a factor in postseason positioning.

The same could not be said about Thursday’s game against Miami, which was suspended because of rain in the ninth inning and the Marlins leading, 2-1.

The decision came after a three-hour, eight-minute rain delay

That game is set to be finished on Monday, beginning at 1:10 p.m., if Miami needs it to make the postseason.

They entered Friday half a game up on the Cubs for the final wild card spot in the National League.

And all of this comes after Tuesday’s game between the Mets and Miami was rained out and made up as part of a doubleheader on Wednesday, which affected the Marlins’ pitching plans as they entered the final weekend of the regular season.

On July 19, Francisco Alvarez had a second straight multi-hit game and brought his OPS up to .839.

Since then, the rookie catcher has struggled at the plate, with a .505 OPS in 51 games.

And it has looked even worse lately, as Alvarez enters the weekend hitless in his last 20 at bats.

Buck Showalter has warned of the catcher wearing down over the course of his first major league season.

So far, the 21-year-old has caught 102 games this season (98 for the Mets and four with Triple-A Syracuse).

Alvarez’s previous career-high as a catcher was 77 a year ago, split between Syracuse and Double-A Binghamton.

When Pete Alonso hit his 45th homer on Sept. 4 with 15 games left to play, the first baseman might make a run at the 50 home run mark for the second time in his career, but he enters the final series of the season with just one homer since then and just three games left to play — weather permitting.

Alonso has had a roller-coaster season and is in another down stretch with just the one homer in his last dozen games.

Over that span, Alonso is just 8-for-49 with 21 strikeouts, but his 46 home runs rank second in franchise history to his 53 homers set in Alonso’s record-setting rookie season of 2019.
